AlGaAs SP2T PIN Diode Switch with integrated bias circuits
Wideband, 80 - 100 GHz
MASW-011111-DIE
Rev. V2
Solder Die Attach
Outline Drawing
All die attach and bonding methods should be
compatible with gold metal. Solder which does not
scavenge gold, such as 80 Au/20 Sn or Indalloy #2,
is recommended. Do not expose die to
a
temperature greater than 300°C for more than
10 seconds.
Electrically Conductive Epoxy
Die Attach
Assembly can be preheated to approximately 125°C.
Use a controlled thickness of approximately 1 mils
for best electrical conductivity and lower thermal
resistance. A thin epoxy fillet should be visible
around the perimeter of the chip after placement.
Cure epoxy per manufacturer’s schedule. For
extended cure times, temperatures should be kept
below 150°C.
Wire / Ribbon Bonding
Wedge thermo compression bonding may be used
to attach ribbons to the RF bonding pads. Gold
ribbons should be at least 1/4 by 2 mil for lowest
inductance. The same gold ribbon or 1 mil dia. gold
wire is recommended for all DC pads.
Dimensions are in µm.
